(1) Setting framework
The framework of the LCS scenarios consists of a target region, the base year of 2005, the target year of 2030, target activities, low-carbon targets, and number of scenarios (Gomi et al.,2010). In this study, the target year is 2030. As an environmental target, we targeted CO 2 from energy use because it will be a main source of CO 2 emissions in Thailand in 2030.
